My invention relates to to clothes line pulleys.

One of the objects of my invention is to provide a clothes line pulleyequipped with power actuated means for operating the pulley.

Another object of my invention is to provide a clothes line pulley ofthe foregoing described character wherein the various components arearranged within a housing and in a manner to form a relatively smooth,compact and portable unit.

A further object of my invention is to provide a clothes line pulley ofthe foregoing described character wherein the housing is constructed ina manner to facilitate assembly of the unit and to permit inspection andreplacement of the various components.

An important object of my invention is to provide a clothes line pulleyunit of the foregoing described character which is simple inconstruction, durable in use, efiicient in operation, economical inmanufacture and which does not require specialized skill in theoperation thereof.

With the above and other objects in view, as will hereinafter appear,the invention consists in the combination and arrangement of partshereinafter set forth and illustrated in the accompanying drawings fromwhich the several features of the invention and the advantages attainedthereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like reference characters designatelike parts throughout the several views:

Figure 1 is a top plan view of my invention.

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Figure 3 is a sectional view Figure 2.

In practicing my invention, as illustrated in the drawing, I provide aclothes line pulley unit comprising an elongated cylindriform housing 5open at its front end and closed at its rear end by means of a rear wall6, with said housing being of a slightly greater diameter at its frontend than at said rear end. The housing is fashioned with a pair ofelongated longitudinally separable sections 7 and 8, respectively, eachprovided on its outer peripheral face with lugs 9 having eyes throughwhich extend bolts 10 provided with nuts 11 for securing the sectionstogether in fixed relation. The rear end of one of said sections isprovided with eyed lug 12 for receiving a hook 13 or other appropriatedevice for supporting the adjacent end of the unit.

Disposed within the front end section of the housing is a pulley 15fixed to a transverse shaft 16 journaled in suitable bearings 17 formedin the sections 7 and 8 and with said shaft having fixed thereto, on oneside of said pulley, a worm gear 18 meshing with a Worm 19 mounted onthe outer end of a drive shaft 20 of a motor 21 secured within thehousing 5 between the rear end thereof and the pulley 15. The axis ofthe shaft 20 extends tangentially with respect to the gear 18 and hasits outer end journaled within a bearing bracket 22 carried by thesection 8 at the front end thereof. The motor is secured in fixedrelation within the housing by any suitable means, for instance, screws23. The motor has connected thereto electric wiring 24 which extendsthrough the housing 5, adjacent the rear end of the latter, and connectsto a source of electrical energy for operating the motor.

pulleys and more particularly taken on the line 33 of Patented Nov. 20,1956 The wire 24 is provided with a switch 25 which controls the flow ofcurrent to the motor and is operable to start and stop the motor andalso to effect rotation of the shaft 20 in either direction. In order tocompensate for the weight of the motor and various other componentsdisposed in proximity to the section 8 of the housing, the section 7 isprovided with a suitable weight 26 to thus balance the housing.

In use, assuming the unit is secured to the hook 13 and a clothes line27 is trained about the pulley 15, the motor is actuated uponmanipulation of the switch to effect movement of the clothes line 27 ina desired direction about the pulley 15, while, upon furthermanipulation of the switch, the motor is reversed to operate the line inan opposite direction.

Without further elaboration, the foregoing will so fully explain theinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service. Moreover, it isnot indispensable that all the features of the invention be usedconjointly since they may be employed advantageously in variouscombinations and subcombinations.

It is obvious that the invention is not confined solely to the useherein disclosed in connection therewith as it may be utilized for anypurpose to which it is adaptable. It is therefore to be understood thatthe invention is not limited to the specific construction as illustratedand described, as the same is only illustrative of the principlesinvolved which are capable of extended application in various forms, andthe invention comprehends all construction within the scope of theappended claims.

What I claim is:

1. In a clothes line pulley assembly, an elongated housing having openand closed ends, and formed with longitudinally extending connectedsections, a shaft transversing said housing and rotatably journaled insaid sections in proximity to said open end, a pulley fixed to saidshaft for receiving a clothes line extending out of said housing throughsaid open end, a gear fixed to said shaft adjacent said pulley, a motorsecured within said housing adjacent one of said sections and saidclosed end and having a drive shaft disposed in tangential relation withsaid gear and inclined relative to the longitudinality of said housing,said drive shaft provided with a worm meshing with said gear foroperating said pulley by said motor, and a weight disposed within saidhousing adjacent said other section for counterbalancing said motor.

2. In a clothes line pulley assembly, an elongated housing havingoppositely disposed ends, a shaft rotatably journaled in said housing inproximity to one of said ends, a pulley fixed to said shaft forreceiving a clothes line extending out of said housing through said oneend, a motor secured within said housing adjacent said other end withits axis disposed in a plane located 011 one side of the longitudinalaxis of said housing, drive means located on said side of thelongitudinal axis of said housing and connecting said motor to saidshaft for operating said pulley by said motor, and a weight fixed tosaid housing on the opposite side of the longitudinal axis thereof forcounterbalancing said motor.
